What gives you the confidence that a theory of everything even exists?
Because the universe exists.
No, no, no. I'm not accepting that. No, don't tell me. No.
So, you should accept the universe, Neil. [laughter]
It could be that quantum physics and general relativity in this universe never come together and there's nothing that would ever bring them together. That's just how the universe is. We we're invoking a philosophical bias of beauty to even assert that there is one theory of everything.
Nope, that's not true.
Oh, tell me.
The universe exists. There is something that happens, right? We don't know the best way of summarizing what happens. The best way of summarizing what happens in the universe might just be to literally list everything that happens. That would be a terribly uninformative theory of the world. We think we can do much better than that. I'm not saying that the theory of everything is simple or elegant or fits on a napkin or a t-shirt or anything like that, but there is some full and complete description of the universe.
